Heroes del silencio

Upon the arrival of the new British Ambassador to Argentina, and while the Vice President is holding a welcome lavish banquet in his honor, a group of terrorist will take over the Argentine Parliament, to avenge an old crime committed at the Falklands War. The dubious past of this somber man will be brought back to live, forced by a fatherless son, who's been dealing with this burden over the years, to finally meet the assassin of his father.
